The sum of three numbers $x$ ,$y$, $z$ is 165. When the smallest number $x$ is multiplied by 7, the result is $n$. The value $n$

babymother [125]

You're given

x + y + z = 165

7x = n

n = y - 9

n = 9 + z

and you want to find xyz.

Solve the last three equations for x, y, and z :

7x = n → x = n/7

n = y - 9 → y = n + 9

n = 9 + z → z = n - 9

Substitute x, y, and z into the first equation and solve for n :

n/7 + (n + 9) + (n - 9) = 165

n/7 + 2n = 165

n + 14n = 1155

15n = 1155

n = 77

Now solve for x, y, and z :

x = 77/7 = 11

y = 77 + 9 = 86

z = 77 - 9 = 68

Then the product is

xyz = 11 • 86 • 68 = 64,328

One pound of grout is enough to grout a tiled area that is 110 sq. Ft. Alyssa's kitchen counter is made up of two rectangular se

Ratling [72]

Answer:

$(10.3(2.5)+3.1(2))\div 110$

Step-by-step explanation:

$A_1$ = Area of 1st rectangle = $(10.3\times 2.5)\ \text{ft}^2$

$A_2$ = Area of 2nd rectangle = $(3.1\times 2)\ \text{ft}^2$

$1\ \text{pound of grout}=110\ \text{ft}^2$

$\Rightarrow 1\ \text{ft}^2=\dfrac{1}{110}\ \text{pound of grout}$

The number of pounds required for the counter top is

$\text{Total area}\times \text{The amount of grout used in 1 ft}^2$

$=A_1+A_2\times \dfrac{1}{110}=(10.3(2.5)+3.1(2))\times \dfrac{1}{110}\\ =(10.3(2.5)+3.1(2))\div 110$

The required expression is $(10.3(2.5)+3.1(2))\div 110$ .

A driver driving a business trip of 240 miles would have reached his destination if he'd been able to drive 12 mph faster than h

mariarad [96]

The average speed of his trip is = 12 mile/ hour

The total distance covered by the driver = 240 miles

The rate at which he traveled = 12 miles per hour

Therefore, the time he used to cover his distance

= 240/12

= 20 hrs

But average speed = distance/ time

= 240/ 20

= 12 miles/ hour

Therefore, the average speed of his trip is = 12 mile/ hour
